'Mutation theory' was given by
1 Hugo de Vries
2 Darwin
3 Lamarck
4 Malthus
Explanation:
Advanced at the beginning of the 20th century by botanist and geneticist Hugo de Vries in his Die Mutations theory (1901-03; The Mutation Theory), mutation theory joined two seemingly opposed traditions of evolutionary thought.

Hugo de Vries is known for_____
1 Mutation alone
2 Saltation theory alone
3 Independently studying Mendels law
4 All of them
Explanation:
Hugo de Vries, in full Hugo Marie de Vries, (born February 16, 1848, Haarlem, Netherlands - died May 21, 1935, near Amsterdam), Dutch botanist and geneticist who introduced the experimental study of organic evolution.

According to Darwin, variations are
1 Heritable and slow
2 Non-heritable and slow
3 Mutational and slow
4 Environmental and fast
Explanation:
Mutations are random and directionless, while, as per Darwin, variations are small and directional. The theory of Darwin's mechanism of evolution starts with the variation between organisms within a genus. Individuals of one generation vary from each other qualitatively.

The source of variations in a sexually reproducing population:
1 Mutation
2 Gene recombination
3 Both (1) and (2)
4 Hybridization
Explanation:
The three main sources of genetic variation arising from sexual reproduction are: Crossing over (in prophase I) Random assortment of chromosomes (in metaphase I) Random fusion of gametes from different parents.
